Read about both and see if you can see anything the two events had in common:

For more information, google both the "panic of 1873" and "the recession of 2008" and you will find more articles.
You may also want to look at the panic of 1893, the panic of 1907, and the Great Depression of 1929-30 to find similarities among all of them, largely due to unregulated speculation and "booms" that went "bust".
